    Abstract: [Problem] In a control system for an electric work vehicle, when a cruise switch is turned on, a vehicle is shifted more quickly to an operation that reflects a driver's intention.[Solution] The control system includes a control device that controls a rotation speed of a traveling motor on the basis of an operation position of a travel instruction tool and a cruise switch that instructs execution of a cruise mode in which a rotation speed of the traveling motor is controlled by an ON operation so that a set vehicle speed is stored, and that traveling is maintained without an operation of the travel instruction tool. The control device executes the cruise mode when the cruise switch is turned on and a predetermined condition is satisfied, cancels the cruise mode when the cruise switch is turned on, but the predetermined condition is not satisfied, and if it is determined that there is no operation of the travel instruction tool after the cancellation of the cruise mode, the rotation speed of the traveling motor is stopped.

    Abstract: [Problem] A power transmission unit that improves quietness of a gear mechanism and prevents a size of the unit from increasing when a brake rotor is installed around an input shaft of the gear mechanism.
    [Solution] The power transmission unit includes an electric driving motor with a motor shaft, a gear mechanism, and an output shaft, which are accommodated in a transmission housing, wherein the power of the motor shaft is transmitted to the output shaft via the gear mechanism. The gear mechanism has a gear shaft rotatably supported on the transmission housing and a first helical gear provided on the gear shaft. The power transmission unit further includes a connecting member provided with a tubular portion fitted to the motor shaft and the gear shaft so as to allow the motor shaft and the gear shaft to synchronously rotate. The connecting member is integrally provided with a brake rotor on the outer periphery thereof.

    Abstract: [Problem] To provide a planetary gear assembly that, while increasing the speed change range of a power-split stepless transmission formed in cooperation a stepless transmission, can reduce the overall size of the power-split stepless transmission. [Solution] The planetary gear assembly according to the present invention includes: a cylindrical transmission shaft, an output shaft inserted into the transmission shaft, first and second planetary gear mechanisms each having a first sun gear supported to the transmission shaft without a relative rotation about an axial line, first and second clutch mechanisms that are placed coaxially with the transmission shaft, and that engage and disengage a power transmission of power to standard rotary speed power input units of the first and second planetary gear mechanisms, and a connection member extrapolated to the transmission shaft with a free relative rotation about an axial line. The connection member, without a relative rotation around an axial line, connects, within the first planetary gear mechanism, a planetary element that is other than a sun gear and a planetary element that forms a standard rotary speed power input unit, with, within the second planetary gear mechanism, a planetary element that is other than a sun gear and a planetary element that forms a standard rotary speed power input unit, and the connection member, meanwhile, is non-rotatable relative to the output shaft about an axial line.

    Abstract: A fork guide groove of a drum member guides a shift fork so that a shifter member is in a reference position not engaged with first and second speed change members when the drum member is placed in a neutral position, is movable between a first speed-change position engaged with the first speed-change member and the reference position when the drum member is placed in a first operational position, and is movable between a second speed-change position engaged with the second speed-change member and the reference position when the drum member is placed in a second operational position. A slider guide groove of the drum member guides a slider member supported by a fork shaft in an axially movable manner so as not to obstruct movement of the shifter member between the reference position and the first speed-change position when the drum member is placed in the first operational position.

    Abstract: A differential gear includes a holder which is provided between first and second pinion gears in a differential case and through which a differential pinion shaft is inserted. An insertion hole is radially formed in the differential pinion shaft. The holder is formed with a fixing hole facing the insertion hole when the differential pinion shaft is inserted through the holder. Due to insertion of a fixing pin through the fixing hole and the insertion hole, the differential pinion shaft and the holder are relatively non-rotatable. Due to the holder being held between first and second side gears, relative rotation of the holder with respect to the differential case is restricted, and the differential pinion shaft is non-rotatable relative to the differential case.

    Abstract: An axial piston machine is capable of suppressing a sudden change in hydraulic pressure in a piston oil chamber upon start and stop to enable the axial piston machine to start and stop smoothly. The axial piston machine includes: a cylinder block including a rotation axis and a plurality of piston oil chambers disposed around the rotation axis; pistons housed in the plurality of piston oil chambers, respectively; and orifices formed in the cylinder block that allow fluid communication between each of the piston oil chambers and an outside of the cylinder block. The orifices are positioned to be opened when the movable swash plate is in the neutral position and to be closed when the movable swash plate is in the operating position. The orifices are closed by outer peripheral surfaces of the pistons when the pistons approach a top dead center position.
